To calculate the NOHDvalue for a specific laser class, use the following formula:
NOHD= Model Constant / MPE
Model Constant includes a consideration of the fan angle for the individual models.
Systems Sold or Used in the USA
Systems that incorporate laser components or laser products manufactured by LMI Technologies
require certification by the FDA.
Customers are responsible for achieving and maintaining this certification.
Customers are advised to obtain the information booklet Regulations for the Administration and
Enforcement of the Radiation Control for Health and Safety Act of 1968: HHS Publication FDA 88-8035.
This publication, containing the full details of laser safety requirements, can be obtained directly from
the FDA, or downloaded from their web site at https://www.fda.gov/Radiation-
EmittingProducts/ElectronicProductRadiationControlProgram/default.htm.
Electrical Safety
Failure to follow the guidelines described in this section may result in electrical shock or equipment
damage.
Sensors should be connected to earth ground
All sensors should be connected to earth ground through their housing. All sensors should be mounted
on an earth grounded frame using electrically conductive hardware to ensure the housing of the sensor
is connected to earth ground. Use a multi-meter to check the continuity between the sensor connector
and earth ground to ensure a proper connection.
Minimize voltage potential between system ground and sensor ground
Care should be taken to minimize the voltage potential between system ground (ground reference for
I/O signals) and sensor ground. This voltage potential can be determined by measuring the voltage
